Exact repeating quantity bundles

The merchant wants Discounty to support exact repeating bundle pricing in quantity campaigns. Their goal is to create offers like 3 for £16, 6 for £32, and 9 for £48, where the discount is applied in fixed groups of 3 rather than continuing the same tier across all additional items once the minimum quantity is reached. At the moment, quantity campaigns work as threshold-based discounts, so once a tier is reached, the same discount continues applying to any extra eligible items. This makes it difficult to create true repeating bundle offers with a fixed total price per group. The merchant needs more precise control so they can run promotions that match their pricing strategy and display correctly for customers at checkout. Adding support for exact repeating quantity bundles would help merchants create more flexible multi-buy offers without relying on workarounds or approximate pricing logic.
